A melee involving a number of players and the two teams' coaching staff was sparked by a late challenge from Ipswich midfielder Jon Nolan.

The Ipswich complaint will allege FA that a home steward physically pushed Lambert backwards as officials moved in to try and break up the confrontation.

Lambert was asked about the incident at his Tuesday press conference, when he said: "It was a lack of class on their behalf; I've never been involved in anything like that at all.

"Some of the things that were said were totally out of order, and I'll fight the corner of this football club.

"There were things that shouldn't have happened, not through our doing. We played a really good game without getting the reward, and that's been the story of our time here. Regarding what I saw and what I've heard, I won't let this club be bullied by anyone."
